Ketamine-depression paper retracted following investigation at Yale

A psychiatry journal has retracted a 2011 paper exploring the use of ketamine to treat patients with severe depression following an investigation at Yale University.

According to the retraction notice, Yale determined that the paper, published in the International Journal of Neuropsychopharmacology, did not accurately describe the research. But the study’s lead author, Gregory Larkin, says he believes the retraction “is wholly unnecessary, serving neither patients nor science.”
